Engine & Turbine Technology
gas turbine, formerly known as 7EA, adjacent to Montana-Dakota’s coal-fired Heskett generating station near Mandan, North Dakota. Operating on pipeline natural gas, the 7E 3-series will generate 88 MW of power when it begins commercial service in 2014. “We needed to add a reliable, proven gas turbine to our fleet, to ensure that we can meet our growing capacity needs,” said Alan Welte, generation director for MDU. “We are confident in GE technology and were looking for a gas turbine that is highly reliable and cost-effective.”
Te 7E 3-series gas turbine features low emissions.
Operating with GE’s Dry Low NOx combustion technology, the 7E 3-series can achieve industry- leading emissions, enabling users to meet today’s increasingly stringent air quality standards (Fig. 2). “Due to the simplicity of its durable architecture, the 7E 3-series gas turbine offers industry-leading starting reliability and can come to full speed in less than ten minutes,” said Paul Browning, president and ceo thermal products, GE Power & Water. “Tis allows the 7E 3-series to excel in peaking power applications, also making it an excellent fit for the quick addition of supplemental power to compensate for the intermittency of renewable energy.“ Finally, Hitachi has received an order from its
Indian partner BGR Energy Systems and NTPC for two steam turbine generators for the Lara super thermal power project – a new 800 MW supercritical coal-fired power plant in the Indian state of Chhattisgarh. NTPC is currently planning the construction of nine supercritical coal-fired power plants at four different sites, and in September 2011 BGR Energy Systems was awarded preferred bidder status for four steam turbine generators at two different sites. Tis order formalises the arrangement for two units at one site. A decision has also been made to proceed with two units at the Darlipali super thermal power project, the other site in the state of Orissa, and a formal order is anticipated in due course. Demand for electric power in India is growing along
with that nation’s rapid economic growth, and this has resulted in power shortages becoming severe in some regions. To overcome this problem, a major increase in capacity up to 330GW, roughly twice the current level, is planned by 2017. Coal-fired power generation currently accounts for about two-thirds of India’s total generation capacity, and it is anticipated that it will remain the primary energy source in the future. Hitachi and BGR Energy Systems established
a joint-venture, BGR Turbines Company Private Limited, in September 2010 to manufacture steam turbine generators for coal-fired power generation to the rapidly growing Indian market. BGR Energy Systems is the lead contractor for this
new order, and Hitachi will supply the key equipment for two steam turbine generators through BGR Turbines. Operation of two units for the Lara project is scheduled to commence in 2016. ●
